15. Memory Organization
The memory organization of the CIP-51 System Controller is similar to that of a standard 8051. There are
two separate memory spaces: program memory and data memory. Program and data memory share the
same address space but are accessed via different instruction types.
15.1. Program Memory
The CIP-51 core has a 64 kB program memory space. The C8051T600/1 implements 8192 bytes of this
program memory space as in-system, Byte-Programmable EPROM, organized in a contiguous block from
addresses 0x0000 to 0x1FFF. Note that 512 bytes (0x1E00 – 0x1FFF) of this memory are reserved for fac-
tory use and are not available for user program storage. The C8051T602/3 implements 4096 bytes of
EPROM program memory space; the C8051T604/5 implements 2048 bytes of EPROM program memory
space, and the C8051T606 implement 1536 bytes of EPROM program memory space. C2 Register Defini-
tion 15.1 shows the program memory maps for C8051T600/1/2/3/4/5/6 devices.
Program memory is read-only from within firmware. Individual program memory bytes can be read using
the MOVC instruction. This facilitates the use of EPROM space for constant storage.
